Large-amplitude electrostatic waves propagating parallel to the background magnetic field have been observed at Earth’s magnetopause by Magnetospheric Multiscale (MMS) spacecraft. These are in region where there is an intermixing of magnetosheath and magnetospheric plasmas. The plasma modeled as a five-component consisting three types electrons, namely, two counterstreaming hot electron beams c...

The nonlinear self-interaction of an electrostatic surface wave on a semibounded quantum plasma with relativistic degeneracy is investigated by using quantum hydrodynamic (QHD) model and the Poisson’s equation with appropriate boundary conditions. It is shown that a part of the second harmonic generated through self-interaction does not have a true surface wave character but propagates obliquel...

We study theoretically the exchange of angular momentum between electromagnetic and electrostatic waves in a plasma, due to the stimulated Raman and Brillouin backscattering processes. Angular momentum states for plasmon and phonon fields are introduced for the first time. We demonstrate that these states can be excited by nonlinear wave mixing, associated with the scattering processes. This co...

The anharmonic oscillator model desribing the propagation of electromagnetic waves in an exterior domain containing a nonlinear dielectric medium is investigated. Local decay of the electromagnetic eld for t ! 1 in the charge free case is shown. If the potential of the oscillating particles is in addition convex it is shown that for arbitrary initial states the electromagnetic eld converges for...

The nonlinear one-dimensional model of controllable photonic crystals is considered. A photonic crystal is formed in a dielectric film on which the electromagnetic pump and signal waves fall. It is shown that the shape of the superlattice is controlled by the variation of the external electrostatic field imposed on the film. Thus it leads to changing boundaries of the allowed and forbidden zone...

Properties of modified plasma waves in non-linear electrodynamics are investigated. We consider a cold, uniform, collisionless, and magnetized model. Initially, we also assume small amplitude the non-relativistic approximation. For electrostatic waves, obtain Trivelpiece-Gould dispersion relation with suitable change frequency analyze stability modes. Furthermore, electromagnetic related to gen...

Telecommunications providers expect products to perform reliably during operation in the field. Achieving the expected hardware reliability is due to an amalgamation of multiple factors. A significant contribution to reliable performance results from the incorporation of specific materials, which are very corrosion resistant and electrostatic discharge (ESD) safe during the design and manufactu...
